天然耐腐性木材抽提液对黄孢原毛平革菌的抑制性研究

摘要

Obtain extracts from Melia azedarach;Sabina chinensis;red-colored Cunninghamia lanceolata and Cunning-hamia lanceolata by simple micro-extraction method,compare antibacterial activity of wood extracts from several decay-resistant tree species to Phanerochaete chrysosporlum (P.c)by plate smearing method and oxford cup method.The re-sults showed that the antibacterial activity of water extracts from M.azedarach,C.lanceolata,red-colored C.lanceola-ta,S.chinensis to P.c and ethanol extracts from S.chinensis and C.lanceolate to P.c were non-significant;and the antibacterial activity of ethanol extracts from M.azedarach and red-colored C.lanceolata to P.c was significant,antibac-terial rate was 52.2% and 40.8% respectively.%采用简单微量抽提法获得苦楝、圆柏、红心材杉木、普通杉木等天然耐腐性木材的抽提液，通过涂布平板法和牛津杯法比较其木材抽提液对黄孢原毛平革菌的抑制效果。结果表明：苦楝、圆柏、普通杉木及红心杉木木材的水抽提液以及圆柏和普通杉木木材的乙醇抽提液对黄孢原毛平革菌（P.c）的抑制效果不明显；苦楝和红心杉木木材的乙醇抽提液对 P.c 具有较显著地抑制性，抑菌率分别为52.2％和40.8％。
